SP3232ECY-L/TR
Overview
The SP3232ECY-L/TR is a high-speed, 2-driver/2-receiver RS-232 transceiver designed for portable and battery-powered systems. It utilizes a high-efficiency charge pump to maintain full RS-232 signal levels from a single 3.0V to 5.5V supply. This part is optimized for power efficiency, consuming only 0.3mA during normal operation and 1uA in shutdown mode.
Why Choose This Part
The device features a low-power shutdown mode that keeps receivers active while drawing only 1uA, allowing for system wake-up on serial activity. Its wide 3.0V to 5.5V supply range ensures compatibility with both modern low-voltage logic and traditional 5V systems without needing multiple power rails.
Applications
Key Specifications
Getting Started
To implement this transceiver, place four 0.1uF capacitors for the internal charge pump and VCC bypass as specified in the datasheet. Ensure the 16-TSSOP footprint includes short traces to the capacitors to minimize ripple. For evaluation, this IC can be integrated into custom PCBs or used with TSSOP-to-DIP breakout boards for breadboard prototyping.
